FLIR OVERVIEW • Forward Looking Infrared Camera • The Department currently has the ThermaCam GasFindIR model. • Without getting into the science on how the camera operates, the camera basically shows the different temperatures of objects depending on their ability to transfer, reflect and maintain heat. • Camera polarity allow for either white hot or black hot images.
Color pallets • The GasFinderIR camera is equipped with two different color pallets • Rainbow a full color spectrum where red is the hottest. • Iron Bow where white is the hottest.
FLIR Overview • The GasFindIR camera transmits Infrared energy in a narrow wave band near 3.3-3.4 micrometers. • The GasFindIR camera has the capability to detect gases that have absorption band or bands at the same wavelength span the camera sees.
Electromagnetic Spectrum Wavelength 3.3-3.4
FLIR Overview • The GasFindIR camera can only detect chemicals with the same wavelengths GasFindIR gas detection webpage Website http//webbook.nist.gov/chemistry • The FLIR camera can detect: Propane Methane Ethane
FLIR Overview • The FLIR camera sees a gas cloud because: • The temperature of the gas cloud is different from the background temperature. • The gas cloud is moving relative to the background. (Freeze Frame) • The gas cloud absorbs IR energy in the wave band the camera is sensitive to.
FLIR Overview • It is not recommended to operate the camera in the rain of fog. Due to background distortion from the weather. • It is difficult to get good images on highly reflective material. (Stainless Steel).
Questions • The Department has a video Thermographer in each of the field offices. • Northern (973) 656-4080 • Central (609) 292-3187 • Southern (856) 614-3601
